Very fun!
It was awesome to play. Only one problem, i got the best weapon of the game and now it's too easy. I have every upgrade and weapon now and get 10k + xp per turn to just spend on more health for me and the base.
A little guide to easily win:
MACHINE GUNS. The best weapon in the game is the Famas, the 5000 xp machine gun. It is the same damage as the minigun but it reloads in the blink of an eye. No other guns compare. So what you need to do is spend NO money on anything but machine guns, upgrade your machine gun as soon as you have enough money to. Once you get the 5000 xp Famas, you are pretty much invincible. Get all the upgrades one by one, and then start upgrading your health and armor. I got every weapon in the game just for kicks, but this is unneccisary as the Famas is the only one i use, but come to think of it switching to the auto shotgun once in a while is good to catch your breath, as the game keeps going and going until you lose...
